Here is the code

 

<?php

require_once("../includes/Sentry.php");

 

$sentry = new Sentry();

if ($HTTP_POST_VARS['user'] != ''){

$sentry->checkLogin($HTTP_POST_VARS['user'],$HTTP_POST_VARS['pass'],4,'welcome.php','failed.php');

}

 

if ($HTTP_GET_VARS['action'] == 'logout'){

if ($sentry->logout()){

echo '<center>You have been logged out</center><br>';

}

}

?>

<?

// Require the classes

require_once('../includes/DbConnector.php');

require_once('../includes/Validator.php');

 

// Create an object (instance) of the DbConnector and Validator

$connector = new DbConnector();

$validator = new Validator();

 

//select which database you want to edit

mysql_select_db("web176-contentms");

 

//If cmd has not been initialized

if(!isset($cmd))

{

//display all the thearticle

$result = mysql_query("select * from cmsarticles order by id");

 

//run the while loop that grabs all the thearticle scripts

while($r=mysql_fetch_array($result))

{

//grab the title and the ID of the thearticle

$title=$r["title"];//take out the title

$id=$r["ID"];//take out the id

 

//make the title a link

echo "<a href='editArticle.php?cmd=edit&id=$id'>$title - Edit</a>";

 

echo "<br>";

}

}

?>

<?

if($_GET["cmd"]=="edit" || $_POST["cmd"]=="edit")

{

if (!isset($_POST["Submit"]))

{

$id = $_GET["id"];

$sql = "SELECT * FROM cmsarticles WHERE id=$id";

$result = mysql_query($sql);

$myrow = mysql_fetch_array($result);

?>

 

<form action="editArticle.php" method="post">

<input type=hidden name="ID" value="<?php echo $myrow["id"] ?>">

 

Title:<INPUT TYPE="TEXT" NAME="title" VALUE="<?php echo $myrow["title"] ?>" SIZE=30><br>

Message:<TEXTAREA NAME="thearticle" ROWS=10 COLS=30><? echo $myrow["thearticle"] ?></TEXTAREA>

<br>

 

<input type="hidden" name="cmd" value="edit">

 

<input type="Submit" name="Submit" value="Submit">

 

</form>

 

<? } ?>

<?

if ($_POST["$Submit"])

{

$title = $_POST["title"];

$thearticle = $_POST["thearticle"];

 

$sql = "UPDATE cmsarticles SET title='$title',thearticle='$thearticle' WHERE id=$id";

//replace theArticles with your table name above

$result = mysql_query($sql);

echo "Thank you! Information updated.";

}

}

?>

I would take this form and make it post to another page like this:

 

<form action="article_edited.php" method="post">
<input type=hidden name="ID" value="<?php echo $myrow["id"] ?>">

Title:<INPUT TYPE="TEXT" NAME="title" VALUE="<?php echo $myrow["title"] ?>" SIZE=30><br>
Message:<TEXTAREA NAME="thearticle" ROWS=10 COLS=30><? echo $myrow["thearticle"] ?></TEXTAREA>
<br>

<input type="hidden" name="cmd" value="edit">

<input type="Submit" name="Submit" value="Submit">

</form>

 

then on the article_edited.php page you would then put this:

 

<?
if ($_POST["$Submit"])
{
$id = $_POST["id"];
$title = $_POST["title"];
$thearticle = $_POST["thearticle"];

$sql = "UPDATE cmsarticles SET title='$title',thearticle='$thearticle' WHERE id=$id";
//replace theArticles with your table name above
$result = mysql_query($sql);
echo "Thank you! Information updated.";
}
}

 

of course this is just a sample of what you would do and you would have to do the mysql connectiosn again on this page. hopefully that helps.

i have noticed that in the last bit of code

<?
if ($_POST["[b]$[/b]Submit"]) <-------Here should only be  
if ($_POST["Submit"]) 

 

now i am having a problem with this part i beleve

 

 $sql="UPDATE cmsarticles SET thearticle='$thearticle' WHERE ID =$id";
$result = mysql_query($sql);
echo "Thank you! Information updated.";

as i get the message Thank you! Information updated. but does not update the data

the code looks like

 

      <? 
// Require the classes
require_once('../includes/DbConnector.php');
require_once('../includes/Validator.php');

// Create an object (instance) of the DbConnector and Validator
$connector = new DbConnector();
$validator = new Validator();

//select which database you want to edit
mysql_select_db("web176-contentms"); 

//If cmd has not been initialized
if(!isset($cmd)) 
{
   //display all the thearticle
   $result = mysql_query("select * from cmsarticles order by id"); 
   
   //run the while loop that grabs all the thearticle scripts
   while($r=mysql_fetch_array($result)) 
   { 
      //grab the title and the ID of the thearticle
      $title=$r["title"];//take out the title
      $id=$r["ID"];//take out the id
       
      echo "<br>";
    }
}
?>
      <?
if($_GET["cmd"]=="edit" || $_POST["cmd"]=="edit")
{
   if (!isset($_POST["Submit"]))
   {
      $id = $_GET["id"];
      $sql = "SELECT * FROM cmsarticles WHERE id=$id";

Try this:

 

<?php
// Require the classes
require_once('../includes/DbConnector.php');
require_once('../includes/Validator.php');

//get the id
$id = $_GET["id"];

// Create an object (instance) of the DbConnector and Validator
$connector = new DbConnector();
$validator = new Validator();

//select which database you want to edit
mysql_select_db("web176-contentms"); 

//If cmd has not been initialized
if(!isset($cmd)) 
{
   //display all the thearticle
   $result = mysql_query("select * from cmsarticles order by id"); 
   
   //run the while loop that grabs all the thearticle scripts
   while($r=mysql_fetch_array($result)) 
   { 
      //grab the title and the ID of the thearticle
      $title=$r["title"];//take out the title
      $id=$r["ID"];//take out the id
       
      echo "<br>";
    }
}

if($_GET["cmd"]=="edit")
{
   if (!isset($_POST["Submit"]))
   {
      $sql = "SELECT * FROM cmsarticles WHERE id='$id'";
      $result = mysql_query($sql);        
      $myrow = mysql_fetch_array($result);
      ?>
      </span></span>
      <form action="editArticle.php" method="POST">
  <input type=hidden name="ID" value="<?php echo $id; ?>">
      <TEXTAREA NAME="thearticle" COLS=40 ROWS=10 class="quoteEdit"><? echo $myrow["thearticle"] ?></TEXTAREA>
      <br>
   
      <input type="hidden" name="cmd" value="edit">
   
      <input name="Submit" type="Submit" id="Submit" value="Edit">
      </form>
   
   <?php } 
   if ($_POST["Submit"])
   {
$thearticle = $_POST["thearticle"];

$sql = "UPDATE cmsarticles SET thearticle='$thearticle' WHERE ID ='$id'";
//replace thearticle with your table name above	

$result = mysql_query($sql) or die(mysql_error());
     
      echo "Thank you! Information updated.";
  
   }
}
?>

 

I cleaned up the code a little bit. You should use <?php instead of <? because it makes it more universal. Secondly you only need to end php ?> when you are switching to html. Also I changed it to get the id without requiring the cmd to be edit. it does not necessarily need to be set to get the id and set it to a variable. if you get any errors please let me know.

ok without the

$_POST["cmd"]=="edit")

i was just getting returned to the editArticle.php with no change so i put that back in and now when i submit an update it changes all the "thrarticle" to my update ? so instead of it updating id 3 it changes id 1,2,3 to all the same article getting closer to the fix tho

The other problem i see is in the last query (sorry just noticed it):

 

if ($_POST["Submit"])
   {
$thearticle = $_POST["thearticle"];

$sql = "UPDATE cmsarticles SET thearticle='$thearticle' WHERE ID ='$id'";
//replace thearticle with your table name above	

$result = mysql_query($sql) or die(mysql_error());
     
      echo "Thank you! Information updated.";
  
   }

 

should be:

 

if ($_POST["Submit"])
   {
$thearticle = $_POST["thearticle"];

$sql = "UPDATE cmsarticles SET thearticle='$thearticle' WHERE id ='$id'";
//replace thearticle with your table name above	

$result = mysql_query($sql) or die(mysql_error());
     
      echo "Thank you! Information updated.";
  
   }

 

the only thing I did was change the ID to id in the query. the fields are case sensitive.

try this:

 

<?php
// Require the classes
require_once('../includes/DbConnector.php');
require_once('../includes/Validator.php');

//get the id
$id = $_GET["id"];
$cmd = $_GET["cmd"];


// Create an object (instance) of the DbConnector and Validator
$connector = new DbConnector();
$validator = new Validator();

//select which database you want to edit
mysql_select_db("web176-contentms"); 

//If cmd has not been initialized
if(!isset($cmd)) 
{
   //display all the thearticle
   $result = mysql_query("select * from cmsarticles order by id"); 
   
   //run the while loop that grabs all the thearticle scripts
   while($r=mysql_fetch_array($result)) 
   { 
      //grab the title and the ID of the thearticle
      $title=$r["title"];//take out the title
      $id=$r["ID"];//take out the id
       
      echo "<br>";
    }
}

if($_GET["cmd"]=="edit" || $_POST["cmd"]=="edit")
{
   if (!isset($_POST["Submit"]))
   {
      $sql = "SELECT * FROM cmsarticles WHERE id='$id'";
      $result = mysql_query($sql);        
      $myrow = mysql_fetch_array($result);

      <TEXTAREA NAME="thearticle" COLS=40 ROWS=10 class="quoteEdit"><? echo $myrow["thearticle"] ?></TEXTAREA>
      <br>
   
      <input type="hidden" name="cmd" value="edit">
   
      <input name="Submit" type="Submit" id="Submit" value="Edit">
      </form>
   
   <?php }

$id = $_GET["id"];
$cmd = $_GET["cmd"];


// Create an object (instance) of the DbConnector and Validator
$connector = new DbConnector();
$validator = new Validator();

//select which database you want to edit
mysql_select_db("web176-contentms"); 

//If cmd has not been initialized

{
   //display all the thearticle
   $result = mysql_query("select * from cmsarticles order by id"); 
   
   //run the while loop that grabs all the thearticle scripts

   {
      $sql = "SELECT * FROM cmsarticles WHERE id='$id'";
      $result = mysql_query($sql);        
      $myrow = mysql_fetch_array($result);
      ?>
      </span></span>
      <form action="editArticle.php?cmd=<?php echo $cmd; ?>&ID=<?php echo $id; ?>" method="POST">
        <TEXTAREA NAME="thearticle" COLS=40 ROWS=10 class="quoteEdit"><? echo $myrow["thearticle"] ?></TEXTAREA>
      <br>
   
      <input type="hidden" name="cmd" value="edit">
   
      <input name="Submit" type="Submit" id="Submit" value="Edit">
      </form>
   
   <?php } 
   if ($_POST["Submit"])
   {
$thearticle = $_POST["thearticle"];

$sql = "UPDATE cmsarticles SET thearticle='$thearticle' WHERE id='$id'";
//replace thearticle with your table name above	

$result = mysql_query($sql) or die(mysql_error());
     
      echo "Thank you! Information updated.";
  
   }
}
?>

 

the code was not being passed to the second page. well it was but by a post and you were not getting if from the post so I changed it so that when it posts it posts the url.
